Aerotaxy® – the path to low-cost, high-efficiency PV nanowires

For years, gallium arsenide (GaAs) semiconductor materials have been developed, tested and used in space and concentrator solar cells because of their high-power conversion efficiency, very low weight to power ratio and excellent stability in extreme conditions. However, due to its prohibitive fabrication costs, the challenge has always remained: how to develop and commercialize low-cost GaAs solar cells?

Aerotaxy suspends active materials in gases intermingled in a precisely controlled environment. The suspended materials bond to form larger, uniform structures. The process generates nanowires within seconds, at yields comparable with semiconductor industry standards, and can produce them on a continuous basis at comparatively low temperatures.

Ultimately, Aerotaxy allows the production of billions of high- efficiency PV nanowires that can be integrated into our efficiency-boosting SolFilm™ solar cell film.

Aerotaxy has its roots firmly established in more than 15 years of world-class research at Lund University, Sweden. The method is the brainchild of world-renowned nanotechnology expert Lars Samuelson, head of NanoLund, the Centre of Nanoscience at Lund University and technical founder of Sol Voltaics.

Sol Voltaics is striving to commercialize Aerotaxy and SolFilm and help realize the promise of delivering low-cost PV nanowires that will significantly increase the power output of solar modules, lower the cost of electricity and provide a pathway to achieve economical clean energy for the world.
